Havin thus described the invention, what i o is claimed as new and desired to be secured by Letters Patent is:

1. In a machine of the character described, the combination of the following elements, a rigid su port for a grinding surface, a rod arrange adjacent each end of said support, said support being ivotally mounted on said rods, and indepenently operable adjusting means for bodily shifting said rods, whereby when the rod at one end of the support is being shifted by the means cooperating therewith the other rod serves as a fulcrum about which the support moves; substantially as described.

2. A machine of the character described provided with a rigid support for a grindin surface, a member on which the forward en of said support is pivotally mounted, means for bodily shifting said member, a pivotal support for the rear or inner end of said grindin surface sup ort, and independent means for bodily sh' ting said rear pivotal support; substantially as described.

3. In a machine of the character described, the combination with a support for a rigid grinding surface, links connected to the inner end of said su port, a pair of levers connected to said lin rs, the free ends of said levers being bent toward each other, a sin le swivel block to which the free ends of said fevers are connected, a nut arranged on said swivel block, a hand wheel on said nut, and a connected to said blocks, nuts on said threaded rods, gears connected to said nuts, and a shaft provided with worms that mesh with said gears so as to rotate them in unison simultaneously and uniformly move said blocks, a pivotal support for the opposite end of said grinding surface, and in( ependent means for bodily shifting said support substantially as described.

5. In a machine of the character described, the combination with a dead plate and a stationarily mounted grinding surface, of means for adjusting said dead plate and grinding surface horizontally, a rigid grinding surface having two ivotal supports at o posite ends thereof, an( means for bodily s ifting said pivotal supports at an les to each other, whereby said rigid grin ing surface may be adjusted vertically or horizontally or obli uely; substantially as described.

n testimony whereof I hereunto afiix my signature in the presence of two witnesses, this twelfth day of March 1907.
